The objective of this study is to evaluate the safety and efficacy of LX211 as therapy in subjects with active non-infectious uveitis
Juvenile idiopathic arthritis (JIA) is often associated with chronic anterior uveitis. Presence of vision threatening complications may indicate immunosuppressive therapy. In this study, the experience with cyclosporine A (CsA) as mono- or combination-therapy is analyzed.
Cataract is a common complication in uveitis patients. Cataract operations with intraocular lens implantation are difficult in these patients because of complication due to the biocompatibility of the intraocular lens. In this study, uveal and capsular biocompatibility of two widely used acrylate intraocular lenses are compared.
This study will evaluate patients with sarcoidosis to understand how the disease affects the body. Sarcoidosis is a disease that results from inflammation of body tissues. The lungs, lymph nodes in the chest, skin and eyes are most commonly affected. As the disease progresses, small lumps, or granulomas, appear in the affected tissues. In most cases, the granulomas clear up, but in cases where they do not heal and disappear, the tissues tend to remain inflamed. Eye inflammation (uveitis) associated with sarcoidosis can cause various eye diseases, sometimes leading to blindness. This study will examine the clinical, immunological and genetic features of ocular sarcoidosis. Patients 6 years of age and older with sarcoidosis may be eligible for this study. Candidates are screened with the following procedures: - Completion of a questionnaire with medical, social and demographic information - Blood draw for laboratory tests - Complete eye examination, including measurement of eye pressure and dilation of the pupils to examine the back of the eye. Fluorescein angiography may be done. This test involves injecting a dye into a vein in the arm. The dye travels to the blood vessels in the eyes. A camera flashes a blue light into the eye and takes pictures of the retina that show whether the dye has leaked from the blood vessels into the retina. Other photographs of the eye may also be taken using a special camera. Participants are followed in conjunction with their local eye doctor as required by the status of their disease. Patients whose disease is stable are seen for an initial examination and followed every 12 months for 3 years.
This study will examine blood cells and other tissue samples from people with uveitis (eye inflammation) to try to gain a better understanding of this condition. It will look at 1) the differences in cells when uveitis is active and when it is under control; 2) the genes that control the functions of these cells during different stages of the condition; and 3) the proteins the cells make at these different stages. Patients 6 years of age or older with an eye inflammation of at least 8 weeks' duration may be eligible for this study. They must currently be enrolled in another NEI protocol for evaluation or treatment of uveitis. Participants will provide blood and possibly eye tissue samples as follows: Blood samples: Blood samples will be drawn, probably from an arm vein, during periods when the inflammation is bad and when it is quiet. No more than 60 mL (about 4 tablespoons) will be drawn at any visit, and no more than eight samples will be collected in 1 year. Tissue samples: For patients who require eye surgery, a sample of tissue or fluid that is removed as a routine part of surgery may be provided to investigators in this study for research purposes. Samples will be collected during patients' visits scheduled as part of their other protocol. The samples will be labeled with a special code number to preserve the patient's identity.
The purpose of this study is to investigate if interferon beta is superior to the standard treatment with Methotrexate for the treatment of intermediate uveitis and macular edema.
This study will evaluate the safety and efficacy of an intravitreal implant of dexamethasone for the treatment of non-infectious intermediate or posterior uveitis.
This study will examine the proteins of people with uveitis, or inflammation of the eyes. Evaluating the vitreous, the colorless transparent substance that fills the eyeball in back of the lens, is now possible with the use of new microtechnology. There is an opportunity to evaluate the kinds of proteins that are present in severe, noninfectious sight-threatening uveitis. Patients ages 18 and older who have been enrolled in the Multicenter Uveitis Steroid Treatment (MUST) study at NIH may be eligible for this study. Up to 200 patients eventually may be enrolled. Researchers will study the vitreous that will be removed from patients' eyes during an operation to insert a steroid implant. The steroid implant is used instead of immunosuppressive therapy, a way to reduce the action of the immune system. Patients will undergo a procedure involving a small hole made in the eye into which the implant is placed. Normally a small amount of the vitreous comes out during that procedure, and in this study, the vitreous specimen will be taken for testing of inflammatory products. At the same time, a small sample of blood, about 1-1/2 tablespoons, will be collected so that the researchers can compare inflammatory products that may be in the blood with those in the vitreous. If a patient needs to have the implant placed again during the study, he or she would be asked permission for collection of the vitreous and blood samples, as previously. Samples collected will not be used to diagnose patients' conditions or to change any treatments being done. All samples will be labeled with special code numbers so that there is no identifying information about patients. This study will not involve examinations or scheduled visits of patients.
This study will determine whether treatment with a combination of the drugs daclizumab and denileukin diftitox can eliminate the need for long-term daclizumab treatment in adult patients with uveitis. Denileukin diftitox kills white blood cells called lymphocytes that cause inflammation and may be the cause of uveitis. Patients 18 years of age and older with uveitis in one or both eyes who are on daclizumab therapy and have not had a disease flareup in 6 months may be eligible for this study. Candidates are screened with a medical history, physical examination, eye examination (including vision test, examination of the front of the eye, and pupil dilation for examination of the retina at the back of the eye), blood tests and a questionnaire about their vision and daily activities. After screening, participants undergo the following procedures: - Daclizumab/ denileukin diftitox treatment. Patients receive their regular dose of daclizumab intravenously (through a vein). The interval between doses is increased by 1 week after each dose. When the doses are 10 weeks apart, the daclizumab is stopped. Patients who experience a flare or uveitis are treated with intravenous denileukin diftitox and possibly local injections of steroids around the eye or increasing or adding other medicines as needed to control the uveitis. - Fluorescein angiography to look for blood vessel abnormalities in the eyes. A yellow dye is injected into an arm vein and travels to the blood vessels in the eyes. Pictures of the retina (the back portion of the eye) are taken with a special camera that flashes a blue light into the eye. The pictures show if any dye has leaked from the vessels into the retina, indicating possible abnormalities. - Ultrasound and urine tests at enrollment and after 1 year to check kidneys, lymph nodes and pelvic area. - Blood tests at enrollment and every 3-6 months for laboratory and immunology tests and other research tests on blood cells to examine the immune response. - Follow-up visits approximately every 6 weeks for 2 years for repeat examinations to determine the response to treatment and drug side effects.
